Possible causes of Dry mouth include:
Medications: Many prescription and OTC medications cause dry mouth, including antihistamines, decongestants, hypertensive medications (for high blood pressure ), antidiarrheals, muscle relaxants, urinary continence drugs, some Parkinson's disease medications, as well as a number of
Age: Even though the dry mouth is not a natural part of aging, older adults tend to take more medications than the rest of the population. Many of the medications taken by seniors cause dry mouth.
Cancer treatment: Radiotherapy ( radiation therapy ) to the head and neck can damage the salivary glands, resulting in less saliva being produced. Chemotherapy can alter the nature of the saliva, as well as how much of it the body produces.
Injury or surgery: This can result in nerve damage to the head and neck area can result in dry mouth.
Tobacco: Either chewing or smoking tobacco increases the risk of dry mouth symptoms.
Dehydration: This is caused by lack of sufficient fluids.
Exercising. or playing in the heat: The salivary glands may become dry as bodily fluids are concentrated elsewhere in the body. Dry mouth symptoms are more likely if the exercise or playing continues for a long time.
Some health conditions, illnesses, and habits can cause dry mouth, such as:
HIV / AIDS
poorly controlled diabetes
sleeping with the mouth open
stroke and Alzheimer's disease, although these are more likely to cause a perception of dry mouth even when the salivary glands are functioning appropriately
Signs and symptoms of dry mouth may include:
cheilitis, or inflammation and fissuring (splitting or cracking) of the lips
cracking and fissuring of the oral mucosa, or inner lining of the cheeks and lips, in which ski at the corners of the mouth may split or become sore
dryness in the mouth
dysgeusia, or taste disorders
fungal infections in the mouth, such as thrush
glossodynia, or a painful tongue
increased need to drink water, especially at ni
inflammation of the tongue, tongue ulcers
lipstick sticking to teeth
more frequent gum disease
more tooth decay and plaque
problems swallowing and chewing - especially and crumbly foods, such as crackers or cereal
problems wearing dentures - problems with denture retention, denture sores, and the tong sticking to the palate
sialadenitis, a salivary gland infection
a sore throat
There are many ways to keep the mouth lubricated and prevent the symptoms of dry mouth.
sipping non-carbonated, sugar-free fluids
chewing gum that contains xylitol
using a carboxymethyl cellulose saliva substitute as a mouthwash may help
avoiding mouthwashes that contain alcohol
not wear dentures during sleep.
eating foods such as carrots or celery
breathing through the nose, as this does not d the mouth to the same extent as breathing through the mouth does.
using a humidifier to add moisture to a bedroom which may help reduce dry mouth symptoms t develop during sleep.
Individuals should avoid:
chewing or smoking tobacco
sugary foods or drinks
acidic foods or drinks
excessively hot or cold drinks
Alcohol consumption should be kept to a minimum or avoided altogether, and caffeine should be only be consumed in moderation.
Treatment of Dry mouth
Often, xerostomia is treated by addressing the underlying causes.
Treatment for dry mouth depends on several factors such as whether the patient has an underlying condition or disease, or is taking certain medications that may be causing dry mouth.
If an underlying cause is found, steps need to be taken to minimize its effect.
Medications: If the dry mouth is thought to be caused by a particular medication, the doctor will either alter the dosage or prescribe another drug which is less likely to cause dry mouth.
Stimulating saliva production: Medication may be prescribed to stimulate the production of saliva, such as pilocarpine (Salagen) or cevimeline (Evoxac).
Experts say that symptomatic treatment for dry mouth typically includes four areas:
increasing the flow of saliva
replacing lost secretions
controlling dental caries
specific measures, such as treating infections
A person with dry mouth should pay special attention to oral/dental hygiene. This includes plaque removal and treatment of gingival infections, inflammation, and dental caries. Brushing teeth and flossing regularly is important.
The doctor or dentist will probably examine the patient's mouth and review their medical history. Blood tests and imaging scans of the salivary glands may also be ordered.
Sialometry: This is a simple procedure that measures the flow rate of saliva. Collection devices are placed over duct orifices of the saliva glands, and saliva production is stimulated with citric acid.
Saliography: This is a radiographic examination of the salivary glands and ducts. It may be useful in identifying salivary gland stones and masses.
Biopsy: A small sample of salivary gland tissue is taken. Often used in the diagnosis of Sjögren's syndrome. If malignancy ( cancer ) is suspected, the doctor may also order a biopsy.
Many doctors report that often, even though the patient complains of severe dry mouth, the oral mucosa appears to be moist. Less frequently, it may be the other way round - the oral mucosa appears dry, but the individual does not complain of dry mouth symptoms.
What is xerostomia?
Xerostomia can have a number of effects on general health and well-being.
Dry mouth is sometimes referred to as xerostomia.
Experts say that xerostomia is usually caused by
inadequate function of the salivary glands.
An individual with xerostomia typically finds it harder to enjoy the food.
Xerostomia is a common problem. It is a frequent side effect of medication, which may improve with a new prescription or an adjustment of dosage.
We all get a dry mouth sometimes - when we are upset, under stress, or extremely frightened. Xerostomia is different - the individual's mouth is dry most of the time.
Some patients may think the dry mouth is a normal part of aging, but it is not. It is, however, more commonly found in older adults. Experts say the main reason is that elderly people take more medications compared with the rest of the population, and some of these medications cause xerostomia.
Xerostomia may be a symptom of a serious systemic disease, such as systemic lupus erythematosus, rheumatoid arthritis, scleroderma, sarcoidosis, amyloidosis, Sjögren's syndrome, Parkinson's, Diabetes, or hypothyroidism. A systemic disease is one that affects the entire body.
Dry mouth is not a disease but a symptom of other conditions.
